I had a Mutec MC-3+ USB Re-Clocker for test. And this improved Sound significantly reclocking the UR signal. But I have Subs in my system, hence the Multichannel Setup. Mutec MC-3+ does not support Multichannel. Mutec gave excellent support, but we could not bring it to live with my Subs integrated in an MC setup. But as I learned that reclocking brought such a dramatic improvement on my UltraRendu, I am now looking after a better performing Streaming device with higher quality clock and performance than UltraRendu with MC support. Hope this gives full context.
I am confused by your question. You are asking about multichannel but the DAC you are using is 2 channel. It might be helpful if you describe your digital chain in more detail. Is this a 5.1 speaker setup? If so, how are you decoding for the other 4 channels?
Thanks but I am sorry that I cannot help you. My experience is with direct connection (which I recommend you try) or with the exaSound Sigma streamer and exaSound DAC. The Sigma Streamer does reliable multichannel with the exa DAC but is not guaranteed to work with other DACs. You might try to reach out to exaSound.
It really isn’t Jin, the RME ADI-Pro is a stereo DAC. The page you link to clearly says that, indeed the clue being the “2” in the title!
They make pro interfaces in multichannel for studios.

You can group multiple zones to play from the same music queue but each zone gets the same file. So a stereo zone will play the same L&R channels from a MCH track. There is no way I’m aware of in Roon to assign a second stereo streamer/DAC and pair of speakers to get the C or LS/RS speaker channels from Roon. I think Kal has stacked multiple stereo DACs to get MCH but I’m not sure that works with Roon.
